The movement inside This reference is built with either calibre. The choice changes the price, the rate and the reserve — nothing else about the watch.
| Base | Seiko NH35 or Miyota 8215, automatic | Swiss clone of the maison's own calibre |
|---|---|---|
| Rate | ±15 to 25 seconds a day | ±5 to 10 seconds a day |
| Reserve | About 40 hours | 55 to 70 hours |
| Balance | 21,600 A/h · six beats a second | 28,800 A/h · eight beats a second |
| Servicing | Any watchmaker can service it; parts are everywhere | Serviced by a specialist; finished as the original is |
| Suited to | Wearing daily, keeping simply, spending less | Matching the reference exactly, and glass casebacks |
The Swiss movement is $50 more. That figure buys the rate, the reserve and a movement that reads correctly through a glass back — not a different watch.
Which we would take. If it is to be worn every day and serviced down the road from you, the Japanese is the honest answer. If it has to survive a loupe against the reference — or the caseback is glass and the movement is meant to be seen — take the Swiss.
The exact base calibre for this reference is confirmed in writing, with the QC film, before anything is dispatched. The two movements, explained

Description
[IWS Factory's Latest Masterpiece of 2021] A new product is here – a replica of the original IWC Portugieser collection watch, featuring time, date, day of the week, leap year display, true moon phase, and month. A perfect replica of all the functions of the genuine article. Welcome to view details:
1⃣️【Case】The watch measures 42mm x 13mm. The case is crafted using top-tier CNC machining, resulting in clean, smooth lines and a high-end finish. It features sapphire crystal on both the front and back, with the front glass boasting exceptional clarity thanks to its coating!
2⃣️【movement】The original Japanese 9015 movement has been modified to be the original Cal.82650 movement. In particular, the movement factory engineer spent a lot of time modifying the position of the balance wheel to achieve the same position as the genuine product. Through a lot of trial and data analysis, the structure has achieved a 99% match with the Cal.82650 movement, and the adjustment method and feel are 100% synchronized.
3⃣️【Dial】 The new watch layout consists of 3 small dials, which are more visually compact and improve readability. The 3 o'clock dial is a clear and easy-to-read calendar dial, the 6 o'clock dial integrates the month dial and moon phase display, the moon phase is accurate and completes one cycle per month, the functions are synchronized with the genuine product, and the 9 o'clock dial has a cleverly designed leap year window, which indicates leap years through L/1/2/3. It is worth mentioning that the leap year function is currently unique in the market, restoring the unparalleled experience closest to the genuine product.
4⃣️【Strap Buckle】Italian small calf leather with an IWC original-grade folding clasp and pin buckle!
Welcome to appreciate IWS Factory's masterpiece of craftsmanship!
